Usecase

Especially challenging if you are in the middle of zypper updates and unsure how far along you need to do something else (even possibly come back to the machine. Knowing what percentage of the progress is completed would be useful.

I don't think we want some other type of indicator (e.g. how much time left) because there's too many variables. But a percentage should be fairly straightforward. We know how many packages are to be downloaded/installed and how many are completed so far.
